I have encountered strange behavior in IIS 7.
There are 4 applications published in IIS and each of them has a specific pool.
Searching the web, I found several pages ( link ) by guiding the configuration of this field using a kind of formula: number of concurrent users x 1.5 = queue size .
So far so good!
The problem is that I have 2 applications that have the pool configured with the value 7000 for the queue size and the error 503 is constantly presented to the user.
Following the reasoning of the formula with which I applied in the configuration (7000 / 1,5) it is as if I had 4666 concurrent users and in fact this system has no more than 10 users, more concurrent.
Does anyone have any idea what might be causing this excessive consumption of requests? Thanks!
